PROBLEM TO BE SOLVED: To provide an elastic wave probe system capable of detecting a discontinuous surface precisely, while eliminating layout restrictions and improving the degree of freedom in probing. SOLUTION: A vibration detection section 5a of a geophone 5 acquires reflection waves RW by elastic waves EW and a vibration value by direct waves within a prescribed amount of time ranging from acquisition start time t0 to t4 based on reference time t1 synchronized to the occurrence time of the elastic waves EW by a built-in timer 5c. Therefore, regardless of radio connection of the geophone 5 to a trigger hammer 3 and a radio transceiver 7, the reference time managed by the geophone 5 is synchronized with the occurrence time of elastic waves by the trigger hammer 3, and an analysis computer 9 can perform a geological analysis by precise vibration value data without any deviation between both the times. Further, since the geophone 5 is connected to the trigger hammer 3 by radio, the geophone can be arranged at a desirable position for a geographical analysis. COPYRIGHT: (C)2010,JPO&INPIT
